https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D209791 --- Comment #1 from Pavel Volkov <pavelivolkov@gmail.com> --- Hello. To generate a new ufsid I used an algorithm from a file: /usr/src/sbin/newfs/mkfs.c 140 time(&utime); 465 sblock.fs_id[0] =3D (long)utime; 466 sblock.fs_id[1] =3D newfs_random(); 1149 /* 1150 * For the regression test, return predictable random values. 1151 * Otherwise use a true random number generator. 1152 */ 1153 static u_int32_t 1154 newfs_random(void) 1155 { 1156 static int nextnum =3D 1; 1157 1158 if (Rflag) 1159 return (nextnum++); 1160 return (arc4random()); 1161 } --=20 You are receiving this mail because: You are the assignee for the bug.=
