Hi all,

I am playing with cfs(4). It works nicely dialing to my fileserver but
fails if I try to use the existing /srv/boot channel.

failed with /srv/boot:

        sceolan% 5.out -d -n -F /srv/boot  -f $cfs -S /n/cache
        <-client: Tversion tag 65535 msize 8216 version '9P2000'
        ->server: Tversion tag 65535 msize 8216 version '9P2000'
        5.out: write failed, inappropriate use of fd

works using dial:

        sceolan% 5.out -d -F /srv/boot  -f $cfs -S /n/cache
        <-client: Tversion tag 65535 msize 8216 version '9P2000'
        ->server: Tversion tag 65535 msize 8216 version '9P2000'
        <-server: Rversion tag 65535 msize 8216 version '9P2000'
        ->client: Rversion tag 65535 msize 8216 version '9P2000'
        <-client: Tauth tag 13 afid 402 uname steve aname 
        ->server: Tauth tag 13 afid 402 uname steve aname 
        <-server: Rauth tag 13 qid (0000000000000192 0 A)
        ->client: Rauth tag 13 qid (0000000000000192 0 A)
        <-client: Tread tag 13 fid 402 offset 0 count 2048

Note: using -n or not makes no differnce to the failed version,
though I would expect to need -n with /srv/boot.

The error occurs on the first write to /srv/boot.

I can mount /srv/boot with mount(1) without problems.

What have I missed?
