Is there ever likely to be a need to have more than two copies of the libs
installed, and in different places?
For example, it might be nice to have a /compat/linux52, a /compat/linux60,
and a plain /compat/linux. Somewhere in the ELF binary you then put
which version of the libs the binary uses, which the emulator uses to
determine which directory to look up in. Any directories not in
/compat/linuxnn get looked up /compat/linux before failing.
There seems to be a slow move to companies only certifying their closed
source apps with specific Linux versions -- for example, I think
CodeWarrior's new IDE is RedHat only (it'll probably run on most Linux
flavours, but that's what they certify it as).
We might well want to have a
/compat/redhat-linux-60
/compat/debian-linux-52
/compat/suse-linux-4
or whatever, all installed at once. Different apps would be configured
(perhaps as an extension of brandelf?) to look in different place as
necessary.
It'll be a fairly pathological case, but it'd be nice if the capability
wasn't designed out of the system from the beginning.
The variant-symlink supporters may now begin their incense burning and
ritual chanting.
