This thread got sidetracked to a different discussion, but I am seeing issues
related to the original question.
I have a simple test app which looks like this in snapcraft .yaml:
apps:
tester:
command: usr/bin/echo-vars.sh
environment:
MY_RO_AREA: $SNAP
MY_RO_AREA_BAD: $SNAP/etc/myro
MY_RW_AREA: $SNAP_DATA
MY_RW_AREA_BAD: $SNAP_DATA/myrw
plugs: [ network, network-bind ]
The command simply echos the values of those variables like this: echo
"MY_RO_AREA = $MY_RO_AREA"
On Ubuntu-core the literal part of the string is doubled:
jwcoates@localhost:~$ snap run tester
MY_RO_AREA = /snap/tester/x1
MY_RO_AREA_BAD = /snap/tester/x1/etc/myro/etc/myro <<<<<<<<<
MY_RW_AREA = /var/snap/tester/x1
MY_RW_AREA_BAD = /var/snap/tester/x1/myrw/myrw <<<<<<<<<
jwcoates@localhost:~$ snap --version
snap 2.23
snapd 2.23
series 16
kernel 4.4.0-53-generic
On Ubuntu classic the $SNAP variables are not expanded (exact same snap
executed):
netop@Snappy-Appliance:~$ sudo snap run tester
MY_RO_AREA = $SNAP
MY_RO_AREA_BAD = $SNAP/etc/myro
MY_RW_AREA = $SNAP_DATA
MY_RW_AREA_BAD = $SNAP_DATA/myrw
netop@Snappy-Appliance:~$ snap --version
snap 2.22.7
snapd 2.22.7
series 16
ubuntu 16.04
kernel 4.4.0-65-generic
Anyone else seeing this ?
Thanks,
Joe Coates

I can verify this. To clarify, this builds and runs fine, but actually results
in the PATH including the string `$PATH` instead of expanding it.
Can a snapd dev comment on this? Is that intended?
