Hi.
The following DASH behaviour seems buggy to me
The only bug here is your expectations.
-----------------
$ export A='\n'
$ echo $A
Passing a literal backslash to echo is non-portable. POSIX even says
so. And bash can match dash behavior:
$ (shopt -s xpg_echo; A='\n'; echo -$A-)

-
eblake@office (0) ~/libvirt
$ (shopt -u xpg_echo; A='\n'; echo -$A-)
-\n-
Fix your shell script to use printf instead of echo if the thing you are
printing might contain a backslash.
