Re: [9fans] pull in 9vx

["andrey mirtchovski" <mirtchovski@gmail.com>]

to summarize (on linux):

directories with 555 permissions (no files can be created in them) in
which the archive needs to write some files:

plan9/mnt/exportfs
plan9/mnt/cons

these are absolutely necessary in order to extract the distribution,
but there are many other files and directories which have no
user-writable bit set, and which may be required for proper operation
while inside plan9 (for example, one can't modify the acme guide
file):

directories in which files can't be created (u-w)

plan9/mail/fs
plan9/tmp
plan9/n/d:
plan9/n/tapefs

so, to uncompress the archive in linux (or osx, or bsd, i presume) do:

$ tar jxvf plan9.tar.bz2 plan9/mnt/cons plan9/mnt/exportfs --mode 755
> /dev/null
[messages about ignored headers]
$ tar jxvf plan9.tar.bz2 --exclude plan9/mnt/cons --exclude
plan9/mnt/exportfs > /dev/null
[messages about ignored headers]

and to fix the files (until they are fixed in the original archive) do:

$ find plan9 -not -perm -200 -print0 | xargs -0 chmod u+w

at this point if you have p9p installed you can run the following
command to ensure that you have everything uncompressed without any
errors:

$ 9 bunzip2 < plan9.tar.bz2 | 9 tar xv
