Details:

File NSData.m: 265. In readContentsOfFile read of file
(/sys/class/power_supply/BAT0/present) contents failed - No such file or
directory

however the same file can be read using "cat" from the command line and
fopen() works just fine on it.

It is not due to the content either, I copied the file with a copy with the
same permissions and it works just fine:
-r--r--r-- 1 root root 4096 May 19 23:22
/sys/class/power_supply/BAT0/present
-r--r--r-- 1 root root 2 May 19 23:32 /home/multix/present

the second file reads fine into a string, the first not.
