Can I simply ignore aufs-util in small systems?

2012-06-16 Thread Guan Xin
Hello,

I am running a small system from memory.
The only mount command involves aufs is:

mount -t aufs -o br:/root/tmpfs:/ aufs /root/new_root

where / is the initrd in squashfs.
Can there be any damage if I don't install aufs-util at all?
Because saving every little bit of memory is very helpful.

Thanks!
Guan

Hello Guan,

Guan Xin:

Aufs-util is essentially necessary in every system where aufs is used.
The most important things are /sbin/mount.aufs and /sbin/umount.aufs
which maintain the aufs pseudo-link and /etc/mtab.
If you don't care about them, then you may be able to choose not to
install them.
See the aufs manual and the aufs-util README file in detail.

Specify: noplink in the mount command and you will still have limited
usability with the loss of many of the options (which are parsed in
the mount helper).

There are some distributions, which use auFS in their Live CD versions,
that do not include the utils.
But about all they can do is create a basic auFS layer stack (which is
all they need to do in a Live CD).
