Well, I can set up a new variable that calling scripts could assert, in
order to force behavior one way or the other. But it would be up to the
calling scripts to create a command line option so that the end user
could override behavior. (although I suppose the end user could set them
as exported environment vars)
I'm thinking something like a list of mount points that are/are-not ACL
capable:
csih_WIN32_VOLS_WITH_ACLS="E:;//server/share;F:"
csih_WIN32_VOLS_WITHOUT_ACLS="C:;D:;//server/othershare"
Then these lists would be checked first, before using getvolinfo for
unspecified mounts. That is:
csih_path_supports_acls()
{
# convert $1 to win32
# check if it starts with any of the volumes
# in csih_WIN32_VOLS_WITH_ACLS (\,/-agnostic)
# and return true
# check if it starts with any of the volumes
# in csih_WIN32_VOLS_WITHOUT_ACLS (\,/-agnostic)
# and return false
return getvolinfo $1 | egrep "FILE_PERSISTENT_ACLS[ ]*: TRUE"
}
