Because I am avoiding "single partition per directory". And a slight
mistake in my original email, it's not just /usr but also /var (and
other root-based directories that will not interfere with boot-up /
operations)
Let me give an example:
Let's say I have /dev/sdc and /dev/sdd, both having single partition
each (/dev/sdc1 and /dev/sdd1).
/dev/sdc1 will be formatted reiserfs mounted into /mnt/Persistent1
/dev/sdd1 will be formatted ext4 mounted into /mnt/Persistent2
Directories not really necessary for daily operations, such as
/usr/src, /usr/portage, /var/db/pkg, and so on and so forth, will each
be a subdir under either /mnt/Persistent1 or /mnt/Persistent2
according to each directory's nature.
Let's take the example of /usr/src ... I can either make /usr/src a
symlink to /mnt/Persistent1/src, or bindmount /mnt/Persistent1/src to
/usr/src
What will be the benefits/drawbacks for bindmount vs symlink?
Rgds,
