Thanks. I committed this.
I was annoyed that you need this "--env=PATH" thing, so I tried this patch:
diff --git a/busybox/GET b/busybox/GET
index 90f2ab1..86a893a 100755
--- a/busybox/GET
+++ b/busybox/GET
@@ -34,7 +34,11 @@ cat <<EOF > usr.manifest
/usr/lib/echo: ->/usr/lib/busybox
/usr/lib/ping: ->/usr/lib/busybox
#
+# Link /usr/bin (in ash's default PATH) to /usr/lib where we put the
executables
+#
+/usr/bin: ->/usr/lib
+#
# test scripts
## /**: \${MODULE_DIR}/test-script/**
then ran "scripts/run.py -e ash" and expected commands to work normally,
and they almost did, except I see this:
/home/nyh/osv.tmp2/osv$ scripts/run.py -e ash
OSv v0.24-425-g77b1f05
eth0: 192.168.122.15
ash: can't access tty; job control turned off
/ # ls
dev libuutil.so tmp zfs.so
etc libzfs.so tools zpool.so
libenviron.so proc usr
ash: ls: not found
/home/nyh/osv.tmp2/osv$
So although "ls" *was* found (in /usr/bin/ls because /usr/bin is linked to
/usr/lib), and ran, after running it, ash still complains it wasn't found
in the path and exits OSv (?).
Do you have any idea why this happens?
Another nitpick it would be nice to fix: If I type a full pathname of a
non-existant command, I get this:
/ # /aaa
terminate called after throwing an instance of 'osv::launch_error'
what(): Failed to load object: /aaa
Aborted
I guess osv_execve() throws an exception which you should catch. Perhaps
osv_execve() should do this catching, and return -1 (and some relevant
errno) to behave more like the original execve?
