However, on Linux it doesn't work if I have much swap and comment out the fstab line ... [rocketmouse@archlinux ~]$ cat /etc/fstab # # /etc/fstab: static file system information # # <file system> <dir> <type> <options> <dump> <pass> # UUID=f386221b-fc9c-434b-b4e7-b3b1b97be8aa LABEL=archlinux /dev/sda9 / ext3 rw,relatime,data=ordered 0 1 # UUID=3e19b702-30ed-4574-91d7-1594fad71842 /dev/sdb7 none swap defaults 0 0 # UUID=4b65ccbf-2219-4734-98fa-16c58d4f60fa #/dev/sda10 none swap defaults,pri=-2 0 0 /dev/sda10 none swap defaults 0 0 #/dev/sda11 /mnt/music ext3 noatime,defaults 0 2 #/dev/sdb12 /home/music ext4 noatime,defaults 0 2 /dev/sda11 /mnt/music ext3 defaults,noatime 0 2 /dev/sdb12 /home/music ext4 defaults,noatime 0 2 #tmpfs /tmp tmpfs nodev,nosuid,size=3G 0 0 ... and on Linux man fstab isn't very helpful. Btw. the default on Linux is half of the RAM, in my case 1.9 GiB, even without the fstab line. Regards, Ralf
