tested with cryptsetup version 1.4.1
When creating a cryptsetup mapper, cryptsetup will create two mappers if the mapper name has characters in it that appear to be bash special characters. Are the characters bash special characters or cryptseup has its own set of characters that trigger this behavior?
example,
1. Create a cryptsetup mapper with the following line: cryptsetup luksOpen abc 'ab*c\d'
/dev/mapper will now have two lines instead of regular one. The first one will be: "/dev/mapper/ab*c\d" and the second one will be "/dev/mapper/ab_c_d".
The existence of these two entries trips the program i am writing and i am wondering why such behavior exists. Why does cryptsetup create two entries and not just one?
I also noticed that these special characters are substituted by an underscore character. The space character on the other hand just cuts off the mapper name. This is an inconsistency and could be a bug.
With the above example, if the mapper name is 'ab c\d'. The second mapper will be "/dev/mapper/ab" and not "dev/mapper/ab_c_d"
