Hi,
This man page contains a list for pretty much every other file system,
with a oneliner description: ext4, XFS is in there, and even NTFS, but
not Btrfs.
Also, /etc/filesystems doesn't contain Btrfs. Anyone know if either,
or both, ought to contain an entry for Btrfs?
The man-page absolutely should. Ideally, that should be kept in sync
with with the mount manpages, but I think they're in separate projects
(mount is util-linux IIRC, while filesystems(5) is part of the Linux
man-pages project).
As far as /etc/filesystems, that should be irrelevant. Of the big
distros, only SUSE, Fedora/CentOS/OEL, and Gentoo use it (I checked
Arch, Gentoo, openSUSE, Fedora, Debian, and Ubuntu, which should cover
at least 80% of users since this is low enough level derivatives won't
be likely to change it), and all it does is dictate what order 'mount -t
auto' will try filesystem types in. All the distros that have it have a
'*' on the last line, which means to check /proc/filesystems, and
therefore will automatically try BTRFS if there's a kernel module for it
(unless the module is blacklisted or prevented from being loaded on boot
automatically).
