2023-02-26file-systems: Validate 'no-diratime flag....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. Tobias Geerinckx-Rice
2022-11-20file-systems: Always do recursive bind mounts....Fixes <https://issues.guix.gnu.org/59185>. * guix/build/syscalls.scm (MS_REC): New variable. * gnu/build/file-systems.scm (mount-flags->bit-mask): Set MS_REC bit when bind-mounting. Ricardo Wurmus
2022-11-03file-systems: Gracefully handle EMEDIUMTYPE in 'read-partitions'....* gnu/build/file-systems.scm (ENOENT-safe): Catch EMEDIUMTYPE and warn. Marius Bakke
2022-10-20file-systems: Support the 'no-diratime' mount flag....* gnu/build/file-systems.scm (mount-flags->bit-mask): Handle 'no-diratime'. * doc/guix.texi (File Systems): Document it. Ludovic Courtès
2022-09-08file-systems: Open files with O_CLOEXEC....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'. Ludovic Courtès
2022-08-10gnu: system: file-systems: Add shared flag....* 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. Oleg Pykhalov
2022-07-01file-systems: Add 'cleanly-unmounted-ext2?'....* gnu/build/file-systems.scm (ext2-superblock-cleanly-unmounted?) (cleanly-unmounted-ext2?): New procedures. Ludovic Courtès
2022-04-08file-systems: Invoke fsck tools with 'system*/tty'....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*'. Ludovic Courtès
2022-04-08mapped-devices: Ensure 'cryptsetup open' gets a tty....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*'.
