Thanks for checking out. I'll gather as much data as I can about these. I
quickly did earlier about mountall, and this one seems off the hook.
On a side note my first try with fstab was strange : before startx, during
the boot, a message indicated that it tried to mount my USB drive, like it
expected to be plugged in before startup. It might be standard behaviour
though.
I thought it was recongnized when plugged in.
Either way, I have barely scratched the surface on fstab, I might be able to
solve this by myself.
Worst case, I still can mount manually, which is the safest solution. I just
wish I could be able to configure automount from a minimal system. I'll try
what you suggested, thanks again :)
