6
701/20/2006
8- replaced partimagehack with ntfsclone
9
1006/20/2004
11- create fifo /var/log/partimagehack-debug.log and empty it
12  to keep ramdisk from filling up
13
1404/13/2004
15- >= should be <= g_loglevel
16
1711/15/2003
18- changed a few []s to char*s
19 
2010/12
21- rewrote partimagehack handling (multiple fifos, chunks, etc.)
22
2310/11
24- partimagehack now has debug level of N (set in my-stuff.h)
25
2610/08
27- call to partimagehack when restoring will now log errors to /var/log/....log
28
2910/06
30- cleaned up logging a bit
31
3209/30
33- line 735 - missing char* cmd in sprintf()
34

36- added run_external_binary_with_percentage_indicator()
37- rewritten eval_call_to_make_ISO()
38
3909/18
40- call mkstemp instead of mktemp
41
4209/13
43- major NTFS hackage

46- paranoid_system("rm -f /tmp/ *PARTIMAGE*") before calling partimagehack
47
4809/11
49- forward-ported unbroken feed_*_partimage() subroutines
50  from early August 2003
51
5209/08
53- detect & use partimagehack if it exists
54
5509/05
56- finally finished partimagehack hack :)
57
5807/04
59- added subroutines to wrap around partimagehack
60
6104/27
62- don't echo (...res=%d...) at end of log_it()
63  unnecessarily
64- replace newtFinished() and newtInit() with
65  newtSuspend() and newtResume()
66
6704/24
68- added some assert()'s and log_OS_error()'s
69
7004/09
71- cleaned up run_program_and_log_output()
72
7304/07
74- cleaned up code a bit
75- let run_program_and_log_output() accept -1 (only log if _no error_)
76
7701/02/2003
78- in eval_call_to_make_ISO(), append output to MONDO_LOGFILE
79  instead of a temporary stderr text file
80
8112/10
82- patch by Heiko Schlittermann to handle % chars in issue.net
83
8411/18
85- if mkisofs in eval_call_to_make_ISO() returns an error then return it,
86  whether ISO was created or not
87
8810/30
89- if mkisofs in eval_call_to_make_ISO() returns an error then find out if
90  the output (ISO) file has been created; if it has then return 0 anyway
91
9208/01 - 09/30
93- run_program_and_log_output() now takes boolean operator to specify
94  whether it will log its activities in the event of _success_
95- system() now includes 2>/dev/null
96- enlarged some tmp[]'s
97- added run_program_and_log_to_screen() and run_program_and_log_output()
