Subject: mount: improve --all documentation
|
|
|
|
Add notes to the --all option description:
|
|
- Historical context: mount -a was originally designed for init scripts
|
|
- Modern usage: systemd-based distributions use systemd units instead
|
|
- Swap handling: swap entries in fstab are silently ignored, use swapon -a
|

+Mount all filesystems (of the given types) mentioned in _fstab_ (except for those whose line contains the *noauto* keyword). This option was originally designed for use in init scripts. Note that many modern systemd-based distributions do not use *mount -a* on boot and instead mount filesystems in a more sophisticated way using systemd units.

The correct functionality depends on _/proc_ (to detect already mounted filesystems) and on _/sys_ (to evaluate filesystem tags like UUID= or LABEL=). It's strongly recommended to mount _/proc_ and _/sys_ filesystems before *mount -a* is executed, or keep /proc and /sys at the beginning of _fstab_.
