* gnu/build/file-systems (canonicalize-device-name): Fallback to tmpfs if spec is "none". Change-Id: Ia55c715d04c7611ba8c979f23f1ad4a8ed2e75b6 Signed-off-by: Ludovic Courtès <ludo@gnu.org>
2023-02-26file-systems: Validate 'no-diratime flag.Tobias Geerinckx-Rice
This follows up on commit c0773455397746b10194bc14c7cef144f4095b65, and adds a comment to avoid this in future. * gnu/system/file-systems.scm (invalid-file-system-flags): Add 'no-diratime to the list of KNOWN-FLAGS.

2022-10-20file-systems: Support the 'no-diratime' mount flag.Ludovic Courtès
* gnu/build/file-systems.scm (mount-flags->bit-mask): Handle 'no-diratime'. * doc/guix.texi (File Systems): Document it.
2022-09-08file-systems: Open files with O_CLOEXEC.Ludovic Courtès
Since this code is run from PID 1, this ensures file descriptors to sensitive files and devices are not accidentally leaked to sub-processes. * gnu/build/file-systems.scm (call-with-input-file): New procedure. (mount-file-system): Use 'close-fdes' + 'open-fdes'.
2022-08-10gnu: system: file-systems: Add shared flag.Oleg Pykhalov
* gnu/build/file-systems.scm (mount-flags->bit-mask, mount-file-system): Handle shared flag. * gnu/system/file-systems.scm (invalid-file-system-flags): Add shared to known flags. * guix/build/syscalls.scm (MS_SHARED): New variable. * doc/guix.texi (File Systems): Document shared flag.

2022-04-08file-systems: Invoke fsck tools with 'system*/tty'.Ludovic Courtès
This ensures those programs, if invoked by shepherd (where standard input is /dev/null), can still interact with the user if needed. * gnu/build/file-systems.scm (check-ext2-file-system) (check-bcachefs-file-system, check-btrfs-file-system): (check-fat-file-system, check-jfs-file-system): (check-f2fs-file-system, check-ntfs-file-system): (check-xfs-file-system): Use 'system*/tty' instead of 'system*'.
2022-04-08mapped-devices: Ensure 'cryptsetup open' gets a tty.Ludovic Courtès
Fixes <https://issues.guix.gnu.org/54770>. Regression introduced in 400c9ed3d779308e56038305d40cd93acb496180. Previously, for an encrypted /home (say), "cryptsetup open" would be invoked by shepherd, with /dev/null as its standard input. It would thus run in non-interactive mode and, instead of asking for a passphrase, fail with: Nothing to read on input. This change ensures it runs in interactive mode. * gnu/build/file-systems.scm (system*/console, system*/tty): New procedures. * gnu/system/mapped-devices.scm (open-luks-device): Use 'system*/tty' instead of 'system*'.

2021-09-23gnu: Don't abuse check-btrfs-file-system to scan.Tobias Geerinckx-Rice

It was for root file systems only due to a bug now fixed. * gnu/build/file-systems.scm (check-btrfs-file-system): Don't invoke ‘btrfs device scan’ here. * gnu/system/linux-initrd.scm (raw-initrd): Do so here if any btrfs file systems are present.

2021-04-23file-systems: read-partition-{uuid,label} don't swallow ENOENT & co.Ludovic Courtès

(partition-field-reader): Remove use of 'ENOENT-safe'. (partition-predicate): Wrap READER in 'ENOENT-safe'.
2021-03-10file-systems: 'mount-file-system' preserves the right mount flags.Ludovic Courtès
Fixes <https://bugs.gnu.org/47007>. Reported by Jelle Licht <jlicht@fsfe.org>. Since commit dcb640f02b1f9590c3bd4301a22bf31bd60c56d4, we could end up applying the wrong mount flags because the (find ...) expression could pick the "wrong" mount point in the presence of bind mounts. * gnu/build/file-systems.scm (mount-file-system): Use 'statfs' to compute FLAGS whe FS is a bind mount.
2021-02-25file-systems: 'mount-file-system' preserves source flags for bind mounts.Ludovic Courtès
Fixes <https://bugs.gnu.org/46292>. * gnu/build/file-systems.scm (mount-file-system): If FS is a bind mount, add its original mount flags to FLAGS.
2020-12-06file-systems: Fix ‘bcachefs fsck’ exit value logic.Tobias Geerinckx-Rice
Bit 1 means the target device was mounted read-only whilst checking. This should never happen in an initrd context but is not an error. * gnu/build/file-systems.scm (check-bcachefs-file-system): Ignore status bits that don't signal an error. Remove the 'reboot-required case.
