The News & mail reader, rna, is written as an ash script, for mulinux:
a brilliantly simple 1m7-fd0 installation. I love the simplicity of
these Italian designs, compared to the Disneyland crap.

Here's my log:-
Run /mnt/p3/rna/rna from mc ==
# ./rna
shift: can't shift that many

>> search 'ash-script' [implemetation of the mail/news-reader]
for "shift" [don't you love mc?!].
== found twice eg. ======
#!/bin/ash

?? perhaps FC1's ash is incompatible ??
Try force use of mulinx/ash ==edit "#!/bin/ash" to "#!mnt/p3/bin/ash"
& test-run == /mnt/p3/bin/ash: can't load library 'libc.so.5'
Try sym-link in 'lib-dir'
Where/what is 'lib-dir' ? Try /usr/bin/printenv ==> doesn't tell.
See where mulinux has libc.so.5 [using mc of course !].
== /mnt/p3/lib/ -> libc.so.5.4.13
? So sym-link <this Partn>/lib/libc.so.5 -> /mnt/p3/lib/libc.so.5.4.13
?! not sure how to use mc to do this !?
Try: ln -s /lib/libc.so.5 /mnt/p3/lib/libc.so.5.4.13
== ln: `/mnt/p3/lib/libc.so.5.4.13': File exists
Try: ln -s /mnt/p3/lib/libc.so.5.4.13 /lib/libc.so.5
== mc shows the required link as the most recent entry/file of /lib/* !
Test run: # ./FC1rna == .: Can't open rna.conf
Seek rna.conf in mulinux-parttion [using mc !]
== found in /mnt/p3/etc == mc: copy to /etc & test run
== ./FC1rna
cat: /usr/rna/welcome: No such file or directory
exec: muless: not found
?!?! OK this 'making the web-of-files available to the script in
the mulinux partition is not practical.

What I want is to redirect all calls to '/root/ to '/mnt/p3'
for the duration of running the RNA script/application.

Is that possible ?

Thanks for info,
