| "grml toram" only helps if I think about it first, not when the job is
| already running and the hard disk is slower than you expected. And there
| are still too many PCs with only 256MB or even 128MB RAM around :)
|
| Unfortunately, doing "grml toram" while the system is working does not
| work. Even if you copy the image file to tmpfs and add it to the union,
| you cannot unmount the original image file since open file references
| will not "jump" to the new location. [I already asked this on the
| unionfs list, but got no hints how to do it, so I think this is
| impossible :( ]. And losetup cannot "move" a loop-mounted file (while
| mounted) either. And I don't know any other way how to archieve this.
|
| But umount -l is a good idea, thanks :)
