E.g. UFS track, nothing. As a matter of fact you can use a cd as a dump device (except that you better keep streaming when writing to the disk...). In the past i tried to dd a UFS partition to a CD. In 2.2.1 times it was even possible to mount it readonly (although i had a panic at some point and i am not sure what was the reason). With 2.2.6 this was not possible anymore. I haven't tried with -current. > dump or tgz track, etc. If not, putting this track offset code in cd9660 > would be a little limiting, no? this is actually a good point, although then you need to resort to the minor number trick (or modify all filesystem codes to let you add an offset to the start of the filesystem). luigi -----------------------------------+------------------------------------- Luigi RIZZO .
