Try not to use ldd for reporting stuff like this since it combines the outputs of all the libraries as well. Use readelf -d for the NEEDED part of the dynamic section or you can use lddtree as well.
Sure lxc container without udev # readelf -d /bin/lsblk Dynamic section at offset 0xcad8 contains 24 entries: Tag Type Name/Value 0x0000000000000001 (NEEDED) Shared library: [libblkid.so.1] 0x0000000000000001 (NEEDED) Shared library: [libc.so.6] 0x000000000000000c (INIT) 0x2540 0x000000000000000d (FINI) 0x94d8 0x000000006ffffef5 (GNU_HASH) 0x2b0 0x0000000000000005 (STRTAB) 0xda0 0x0000000000000006 (SYMTAB) 0x338 0x000000000000000a (STRSZ) 1233 (bytes) 0x000000000000000b (SYMENT) 24 (bytes) 0x0000000000000015 (DEBUG) 0x0 0x0000000000000003 (PLTGOT) 0x20cc98 0x0000000000000002 (PLTRELSZ) 2160 (bytes) 0x0000000000000014 (PLTREL) RELA 0x0000000000000017 (JMPREL) 0x1cd0 0x0000000000000007 (RELA) 0x1400 0x0000000000000008 (RELASZ) 2256 (bytes) 0x0000000000000009 (RELAENT) 24 (bytes) 0x000000000000001e (FLAGS) BIND_NOW 0x000000006ffffffb (FLAGS_1) Flags: NOW 0x000000006ffffffe (VERNEED) 0x1350 0x000000006fffffff (VERNEEDNUM) 2 0x000000006ffffff0 (VERSYM) 0x1272 0x000000006ffffff9 (RELACOUNT) 86 0x0000000000000000 (NULL) 0x0 lxc host with udev # readelf -d /bin/lsblk Dynamic section at offset 0xca78 contains 26 entries: Tag Type Name/Value 0x0000000000000001 (NEEDED) Shared library: [libblkid.so.1] 0x0000000000000001 (NEEDED) Shared library: [libudev.so.0] 0x0000000000000001 (NEEDED) Shared library: [libc.so.6] 0x000000000000000c (INIT) 0x2c58 0x000000000000000d (FINI) 0x9d08 0x0000000000000004 (HASH) 0x2b0 0x000000006ffffef5 (GNU_HASH) 0x7f8 0x0000000000000005 (STRTAB) 0x13b8 0x0000000000000006 (SYMTAB) 0x8a8 0x000000000000000a (STRSZ) 1354 (bytes) 0x000000000000000b (SYMENT) 24 (bytes) 0x0000000000000015 (DEBUG) 0x0 0x0000000000000003 (PLTGOT) 0x20cc58 0x0000000000000002 (PLTRELSZ) 2280 (bytes) 0x0000000000000014 (PLTREL) RELA 0x0000000000000017 (JMPREL) 0x2370 0x0000000000000007 (RELA) 0x1aa0 0x0000000000000008 (RELASZ) 2256 (bytes) 0x0000000000000009 (RELAENT) 24 (bytes) 0x000000000000001e (FLAGS) BIND_NOW 0x000000006ffffffb (FLAGS_1) Flags: NOW 0x000000006ffffffe (VERNEED) 0x19f0 0x000000006fffffff (VERNEEDNUM) 2 0x000000006ffffff0 (VERSYM) 0x1902 0x000000006ffffff9 (RELACOUNT) 86 0x0000000000000000 (NULL) 0x0
