I recently bought an external usb drive for my music collection. I formatted the drive as FAT, and set it to mount in the same directory where my music was via the PCLOS CC. At first I noticed that I had no write permission, but after a little internet search this was easily solved: I added the "umask=002,gid=users" options in the new fstab line. Perfect. Amarok doesn't even know it reads a different drive.
However now my desktop boots in command line mode. It's interesting that it does reboot in graphic mode.
I understand that's a minor issue, but I wonder if this is to be expected. It might not even be because of PCLOS, but because of my motherboard capabilities (I remember I had difficulty to boot from a usb drive in the past). Note that I made a test with my usb stick before buying the new drive, and it also caused text mode boot. I doubt it matters, but I'm still using KDE3.
