- Ok, the joke's on me. I'll try dump. Now on to Joe Yao's articles.

- ? Easy enough:
- ? [%$] su
- ? Password:
- ? # mount
- ? / on /dev/disk-0
- ? /prime on /dev/disk-1
- ? /prime/secundus on /dev/disk-2
- ? # unmount /dev/disk-2
- ? # cd /prime
- ? # tar xv

- Find on BSD4.3 has -xdev, and others have -prune. It is often desirable
- to restrict searches to a single file system. Besides, to unmount /usr,
- you have to kill all the daemons, and then the only editor you have is ed.

- ? Guy's arguments are mostly good, especially when reasoning about
- ? the byte-order problem. It should perhaps be noted, though, that
- ? cpio pre-dates tar, and that there are probably numerous systems
- ? "out there" that have cpio but not tar. This, at least, seems to
- ? be one of the arguments used by X/OPEN.
-
- Saying cpio predates tar might be strictly true, but tar hit the streets
- first. Do you know of any UNII that have cpio but not tar?
