[9front] Staying up-to-date

[Thomas Nemeth <tnemeth@free.fr>]

    Hi.

    I've read the FQA and some other documentation a lot and I'm amiss
    about why my system upgrade script does not work the way I intend
    it to work. I certainly don't know enough about the specifics and
    peculiarities of rc.

    I made a script, named sysupgrade, that does what's in dash1,
    section 5.2.2: "Building from source".

------8<------8<------8<------8<------8<------8<------8<------
#!/bin/rc

sysupdate

# create any missing directories needed for the build
cd /
. /sys/lib/rootstub

# build everything
cd /sys/src
mk install
mk clean

# build manpage indices
cd /sys/man
mk
------8<------8<------8<------8<------8<------8<------8<------

    But, unfortunately it fails to execute everything so I usually
    type them one by one... (well, today the compilation fails anyway).

    Can someone explain or tell me what I did wrong ?

Thomas.
